E.g. exhausted live stand-up comedian from Liverpool? (5)

'e g exhausted' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'live stand-up comedian from liverpool?' is the wordplay.
'live' becomes 'l' (electrical abbreviation).
'stand' means one lot of letters goes inside another.
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'comedian from liverpool?' becomes 'eyas' (I can't justify this - if you can you should believe this answer much more).
'eyas' back-to-front is 'saye'.
'l' put inside 'saye' is 'SAYLE'.

Can you help me to learn more?
